Slim in appearance but powerfully built the A28 offers an ideal balance between power delivery and size. Sophisticated control electronics offer complete control over seven sources. 75 watts per channel provide enough drive and control for use with some of the world’s best high performance loudspeakers. The A28’s flexibility is due to its microprocessor control and intelligent software which provides unique features without compromising amplification performance.
